This research aims to verify the accuracy, stability, and clinical usefulness of artificial intelligence (AI) algorithms for measuring heart function through echocardiography. The study involves collaboration with multiple medical centers and focuses on comparing AI measurements with those done manually by physicians of different experience levels. It also explores whether AI can reduce the time needed for echocardiogram analysis and improve clinical workflows, while assessing AI's performance in complex heart conditions such as cardiomyopathy and valve disease. The study collects echocardiographic data using Mindray ultrasonic machines, with AI and physicians at each center measuring key heart parameters including left and right ventricular size and function. AI and intermediate doctors complete measurements within one day of data collection, while senior physicians at the main research unit finalize their assessments within one month. The goal is to establish a standardized reference system for AI in ultrasound measurement and promote its use across various medical institutions. Participants aged 18 to 80 years with specific heart conditions or normal hearts are involved. Researchers measure heart chamber sizes and functions through echocardiography, comparing AI and physician results for consistency and accuracy. The study also monitors how AI-assisted measurements could optimize diagnosis time and medical resource use. The total duration of participant involvement depends on data collection and measurement timelines, with ongoing analysis to support AI's clinical application in cardiovascular care.

Researchers are investigating the effects of a medicine called BI 690517 in combination with empagliflozin for adults with chronic kidney disease who are at risk of their condition worsening. This study includes people both with and without type 2 diabetes and those already taking certain kidney-related medicines like ACE inhibitors or angiotensin receptor blockers. The goal is to understand if adding BI 690517 helps protect kidney function and reduces risks related to kidney failure and heart problems. This is a Phase 3 clinical trial conducted over about 3 to 4 years. The study has two parts. First, participants receive either empagliflozin or a placebo similar to BI 690517 for at least six weeks, while continuing other indicated treatments like ACE inhibitors or ARBs. In the second part, participants are randomly assigned to take either BI 690517 tablets or placebo tablets once daily alongside empagliflozin for the rest of the study. The placebo tablets look like BI 690517 but contain no active medicine. Participants have regular visits to the study site, about four times in the first six months, then every six months afterward. During these visits, doctors monitor kidney function, heart health, blood pressure, weight, and any side effects. Blood and urine samples are taken to track health changes. The main outcomes measured are the time until worsening kidney disease, hospitalization for heart failure, or cardiovascular death. The study ends when a certain number of these events have occurred.

Researchers are evaluating the safety and effectiveness of LT3001 in treating adults who have experienced an acute ischemic stroke. This phase II, multicenter, randomized, double-blind, placebo-controlled study aims to understand how LT3001 impacts neurological impairment caused by stroke. Participants are between 18 and 80 years old and have a specific range of stroke severity based on the NIH Stroke Scale. Participants will be randomly assigned to receive either a high dose or low dose of LT3001 or a placebo, all given through intravenous infusion. The treatment must start within 24 hours after stroke onset. The study compares these groups to assess how LT3001 might help in acute ischemic stroke management. During the study, participants will be monitored for about two years to track any adverse events and evaluate safety. Researchers will assess neurological symptoms and overall health status through clinical evaluations and safety monitoring. Participants must consent to the study and agree to contraception guidelines if applicable. The long-term follow-up ensures careful observation of treatment effects and participant well-being.
